This made-for-TV movie, one of a series that brought back James Arness in the role of Marshall Matt Dillon from the long-running TV Western serial Gunsmoke, finds Dillon on the trail of an angry young man whose mother was killed during a robbery of a stagecoach. The boy has sworn vengeance against the men who murdered his mother, but Dillon is determined to see the bandits brought to trial -- and to prevent the headstrong young man from being killed by the bloodthirsty gunmen. As Dillon hits the trail, he's joined by a stranger named David Healy (Bruce Boxleitner), whose eagerness to help doesn't quite disguise the fact that he has a secret agenda of his own. Gunsmoke: One Man's Justice, the fifth and final movie in the revived Gunsmoke series, was first aired on February 10, 1994.
